| Zusammenfassung |
| Mediterranean areas are characterized by a strong spatial variability that
makes the soil hydrological response highly complex. Moreover, Mediterranean
climate has marked seasons that provoke dramatic changes on soil properties
determining the runoff rates, such as soil water content or soil water
repellency (SWR). Thus, soil hydrological and erosive response in
Mediterranean areas can be highly time- as well as space-dependant. This study
shows SWR, aspect and vegetation as factors of the soil hydrological and
erosive response. Erosion plots were set up in the north- and the
south-facing hillslope and rainfall, runoff, sediments and SWR were
monitored. Soil water repellency showed a seasonal behaviour and it was
presented in three out of four microenvironments after the summer,
disappearing in the wet season. In general, runoff rate was higher in shrubs
patches (0.47 ± 0.67 mm) than in inter-shrub soils (1.54 ± 2.14 mm),
but it changed seasonally in different ways, depending on the aspect
considered, decreasing in the north-facing hillslope and increasing in the
south-facing one. The main factor determining the hydrological and erosive
response was the rainfall intensity, regardless of the rainfall depth of the
event. This response was modulated mainly by SWR in the north-facing
hillslope and the vegetation pattern in the south-facing one. |
